A 1912 experiment found that if an electromagnet spins on its long axis, its magnetic field does not rotate along with it. And while the Earth spins, its rotational axis doesn’t quite line up ...

"If the effect is real and scaling behaves the way our equations say, then the possibility becomes real," Chyba told Newsweek ...

This effect occurs when a voltage is applied along a thin conducting sheet of material while a magnetic field is applied perpendicular to its surface. Relatively low electric current The electric ...

But Faraday’s experiments were a resounding failure and a few years later, physicists worked out why. Any movement of a conductor through this magnetic field does indeed produce a force on the ...

This current is caused by an electric field inside the wire, so we could say that a changing magnetic field produces an electric field. But how do you make a magnetic field? Two ways: First, an ...

That electric current generates its own magnetic field, and here is the kicker: the 'induced' magnetic field always faces the opposite direction to that of the magnet that produces it.

Once the WHAM team chilled the magnets down to operating temperature and applied a strong electrical current, the high-temperature superconductors produced a 17 tesla magnetic field.
